int main()
{
/*Half of the window size for the census transform*/
int hWin = 1;
int bitlength = 0;
if ((2*hWin+1)*(2*hWin+1)%32 == 0)
{
bitlength = (2*hWin+1)*(2*hWin+1)/32;
}else {
bitlength = (2*hWin+1)*(2*hWin+1)/32 + 1;
}
cout<<"hWin: "<<hWin<<"; "<<"bit length: "<<bitlength<<endl;
github下的源码，这里windowsize指的应该是支持窗口，但这里%32不太懂表达什么意思，这个32表达什么，bitlength又大概表达什么意思呢？
望大神赐教，好人一生平安！
